Heavenly Sins - Between Life & Death (Paperback)

With one of his lovers imprisoned in the Underworld, Mac has no
choice except to go where most angels fear to tread. With Tristan
imprisoned in the Underworld, the menage is broken. Angels are
forbidden to enter the demonic domain and while Mac has been
breaking rules in recent months, he doesn't have the power to enter
the Underworld. Alastor is still unsure about his position in the
relationship following recent revelations, but he cannot walk away
when he is the only real link between his two lovers. Splitting his
time between Mac and Tristan, he hopes they can soon find a way to
reunite the two men in his life. As time moves on, Alastor realizes
he is struggling to satisfy Tristan's thirst for sex. His lover
needs more than he can give him and craves Mac in his bed. Mac
still believes he can complete his mission to save his two lovers,
but with one of them out of his reach, it is going to be far from
easy. During their time together they have made plenty of enemies,
including one who would seek to separate them forever, even if it
means biding his time until Alastor and Tristan are at their most
vulnerable, when even the love of an angel can't save them."
